Even cuts top and bottom.

Postpone your plumber, get the right sized sink. Anything else is a bodge.

Ideally you'd use a mechanical fixing but with a bit of Dow 785 it won't move.

Tank it with the Mapei kit from Screwfix and tile away.

Why would you use an adhesive that the manufacturer specifically says is unsuitable for the tiles that you're fixing? What's a small bag of rapidset to do the job right? £10?

I'd say I moved over to tanking all wet areas about four years ago. No failures as yet. It's a non biodegradable membrane with mechanical protection (i.e. behind tiles). No reason to think it should fail.

Can't help unfortunately but it's what I use on all my installations. Mapei make quality products.

Remove the laminate. Overlay the chipboard with 'no more ply' glued and screwed. Tile onto that with a decent quality powdered cement based flexible adhesive and grout.

Assuming 7 days in a habitable/heated house I’d say you’d be pretty safe with easifill. When you fill go slightly proud so you can sand back/feather it in. Ideally Mist the chase with watered down contract followed by a couple of coats of vinyl matt.

Hard to say with easy-fill. If you were using bonding/hardwall and multi-finish you would be able to see. I know for screed they say 1mm per day. All depends on the depth of the chases, the temperature, humidity etc. With a contract it wouldn't matter as it can breathe. Vinyl and you're sealing...

They do work. They're just not waterproof.

Hardie isn't waterproof.

Which board are you using that is waterproof?

Tanking the joints of cement boards won't make it waterproof. Cement boards aren't waterproof. Just use regular plasterboard and tank it all. Far cheaper.
